Authentication
This chapter shows you how to set up subscriber authentication on the VSG.
6.1 Authentication Overview
You can set the VSG to authenticate subscribers in a number of ways:
• User agreement
• CAS (Central Authentication Service)
• Built-in authentication
• Remote RADIUS server
By default, subscriber authentication is disabled. This allows all subscribers to access the
Internet without entering account username and password.
6.1.1 User Agreement
In cases where authentication is not required and anyone can access the Internet through the
VSG, you can set the VSG to require users to
accept a service usage agreement before they can
access the Internet.
6.1.2 CAS (Central Authentication Service)
The Hilton Group Corporation developed the High Speed Internet Access (HSIA) service to
provide Internet access service across its entire Hilton Group hotels.
In order to use the HSIA, hotel guest(s) must be authenticated through the proprietary CAS.
The CAS performs both user authentication and accounting.
Figure 28 CAS Example
The following summarizes the communication steps before Internet access is allowed.
